[Shotimes] Clicking Noise

[Steve Weinrich]

The slack is due to the lack of oil pressure in the tensioner assembly while
just sitting there.  As the camshaft lobes make maximum lift on the valves
then release during rotation, that causes the tension on the camshaft and
its chain to vary greatly.  I do not know if this will be a problem when the
engine is actually run under its own power and oil pressure is actually up
to the tensioner.

As I recall, the right bank tensioner has become difficult to locate as a
replacement part.  Hope you don't need one.
